Error on page .../SysInfo/Composite/General. Could not manage 'admins' anymore

[frk]

Hello community,

I'm not able to manage Admins anymore. Log shows me:

DEBUG> ManageAdmins.pm:89 EBox::SysInfo::Model::ManageAdmins::row - Fehlendes Argument: id at Fehlendes Argument: id at /usr/share/perl5/EBox/SysInfo/Model/ManageAdmins.pm line 8

Bevor this, I tried to remove an Admin. Has anybody a hint to manage this mistake.

Environment: Zentyal: 4.1.5

Thanks for any hint

Best regard
Tom
